Answer:
when the nuclear war started
Explanation:
The Cuban Missile Crisis occurred in 1962 between the Soviet Union and the United States when the Soviets supplied nuclear weapons to Cuba to forestall any future invasion and this caused military tension between the two nations.
However, it was eventually de-escalated through diplomatic means and the Cubans were told to use their nuclear weapons when the nuclear war started, which thankfully, didn't.
General George Washington was appointed as commander-in-chief of the colonial army, and, as you already know, later became the first president of the United States of America.

Marginal costs. Keep in mind that marginal means on the edge of something, so the cost of producing one more unit would be on the edge. Hope this explanation helps.
